Emerging free iOS apps: Dragon Story, I’d Cap That and Are You Smarter Than a Fifth Grader?

Once again, this week’s free iPhone apps chart is led by an independent developer. This week Cody Kolodziejzyk takes the No. 1 spot with his photography app, I’d Cap That. The app allows users to add random, often crude captions to pictures from their photo library and share them via email and Twitter.

Last week’s leader, Tobi Apps‘ puzzle/room escape game 100 Floors continues to hold its popularity, dropping only to No. 3 on the free iPhone charts. The difficult game, which requires users to figure out how to advance through a series of elevators has even inspired its own unofficial walkthrough — Blue Pill Inc’sCheats for 100 Floors 🙂 which takes the No. 5 spot on the free app charts.

On the iPad charts, Ludia’s latest game show-inspired title Are You Smarter Than a Fifth Grade & Friends takes the No. 1 spot. The free-to-play game allows players to compete with up to six of their Facebook friends to answer elementary school trivia questions, but players only get a certain amount of free games a day. Players wishing to play more must purchase stars, the game’s in-app currency.

Further down the charts, Team Lava’s dragon-raising sim Dragon Story also makes a strong showing, hitting No. 17 on the iPhone charts and No. 6 on the iPad charts. The game, which is similar to Backflip Studios’ DragonVale, challenges players to raise and breed a variety of magical dragons. The game was released in the U.S. App Store on May 13.
